<p>Disclosed are a liquid concentrate for a cleaning composition, a cleaning composition using the same, and a cleaning method for the cleaning of flux residue, solder paste, etc., which are highly safe for the environment since a predetermined amount of water is added later, which exhibit excellent cleaning properties and further provide excellent regeneration efficiency. The liquid concentrate for a cleaning composition, etc. for cleaning an object to be cleaned is used in combination with water as well as being added with a predetermined amount of water and used in a clouded form, and comprises as organic solvents a first organic solvent and a second organic solvent, wherein the first organic solvent is a prescribed hydrophobic glycol ether compound or the like, and the second organic solvent is a prescribed hydrophilic amine compound. The content of the second organic solvent is within the range of 0.3 to 30 parts by weight per 100 parts by weight of the first organic solvent, and the content of the organic solvent the boiling point of which exceeds 190°C is within a predetermined range.</p> |
